A cynic may question the research and ask if life has really changed that much for teenage girls, certainly enough to provide any real insight.

When I left school in 2011, my peers and I worried about exam results, boyfriends, girlfriends, whether we were cool enough for this, or clever enough for that. Whether we would get into university, survive it, or fail it all entirely.

We worried a lot about getting in to university because tuition fees were about to treble, and failing exams meant stumping up £9k a year for the following year, which just wouldn’t do.

Those worries, with a few exceptions, haven’t changed.

When my parents’ generation were growing up, teenage girls (I'm reliably informed) worried about whether 'hot George' at school would ring or not, because they had to wait physically next to the telephone.

University pressure was less of a worry, because it wasn’t such an expectation that you’d go – nor is it now, for everyone, but it is for some.

When my mother tells me – as she is wont to, at every available juncture – that ‘nothing has changed since I was your age’ she is half right. In a way, it hasn’t – the base level stuff, the mechanics of life. But the culture has.

Partly, this is prompted by Apple, Samsung and Google. Look around a tube carriage at rush hour (as I did when I was writing this), and people are engrossed in technology. Life is as technology centred for teens as it is for adults.

That culture feeds into anxiety and pressure for teenagers in 2015.

Now, if they like, teenagers can date on their phones, talk on their phones, and arrange to sneak out of the house on their phones. They can do their homework using their phones; indeed, some schools are increasingly making use of them as teaching tools.

When I was 18, Snapchat didn’t exist, and we hadn’t found Instagram, the ultimate humble-bragging, anxiety-causing app of joy. I had Facebook and Twitter (MySpace, RIP), and I know I stressed out when a boy didn’t text me back, but these things were not central possessions in our lives.

Even that much exposure to technology, which now seems pathetically limited, can make one anxious. Now, so many young people have smart phones (poorly named), no longer are bullies limited to physical classroom space, or the taunting walk home from school. They are brought into the house, upstairs and into bedrooms.

Exam worries and comparable selfie-taking also manifest themselves on social networks. And so too does the honesty that comes with exposure to these technologies. It isn’t the phone itself that’s at fault, but the culture in which it prevails.

Our online culture promotes honesty – or faux-honesty – by making sure that everyone has a voice. YouTube has bred a new generation of role models,those like Zoella, Tanya Burr and Louise Pentland who talk openly about their emotions on camera for millions of viewers.

And praise be to these young women, doing their bit. It’s important, what they do, because mental health and anxiety is continually shoved under a carpet, and pushed away.

But it does not excuse the fact that young girls have been forever vulnerable to anxiety's clutches. Our culture, as empowering, vibrant and exciting as it can be for teenagers, is also dangerous. Sure, that honesty means that information like this can come to light, but, sadly, it is self-perpetuating.

Technology makes young people more anxious, but it also allows them to speak openly about how they feel. It is self-defeating, too.

Have young girls become more anxious, more self-conscious, and more troubled? I’m not convinced.

Have they found a voice to tell us about it? They sure have.

The ability to talk about anxiety, is empowering. But the root cause behind it just might be the device on which it is reliant, and who can say which is more terrifying.
